Sunderland are to make an £8m bid for Fulham striker Bobby Zamora.
The 30-year-old has found himself out of favour at Craven Cottage this season under manager Martin Jol.
However, the Black Cats are facing a struggle to get him to leave London.
The Wearside club have also been linked with a move for Rangers striker Nikica Jelavic in the January transfer window.
